Outside of the X-Men's disco-themed hero Dazzler, you'd be hard pressed to find another character whose look is quite as dated as Jericho's. His design is classic George Perez, but it's also very much like something right out of Jesus Christ Superstar. His role as a mute pacifist character and son of the Titans greatest enemy definitely served the story, but he's not a character meant to stand on his own. The fact that Nightwing's very first appearance in costume is a split panel page with Joseph's first appearance as Jericho has always been a blemish on that moment. He had a far more modern costume when he returned to the team many years later, and we've decided that this should just be his standard outfit. It spares us the trouble of suffering through his completely pointless return.

In the comics, Jericho was possessed by the tainted souls of Raven's home dimension of Azerath, which corrupted him, turning him into a villain. Deathstroke killed him as an act of mercy, saving him from himself. We've shifted that a bit, stacking his death into Terra's betrayal of the team in order to make it far more tragic. Deathstroke is no longer performing an act of mercy; It's now an incredibly cold act, killing his own son. It's the sort of tragedy that can bring apart the end of the team. If for no reason other than this, Jericho's role in the Titans is incredibly important.
